Abstract
The invention relates to a low-carbon equivalent high strength and toughness cast steel. The low-carbon equivalent high strength and toughness cast steel comprises the following chemical components in percentage by weight: 0.12 to 0.18% of C; 0.30 to 0.60% of Si; 0.90 to 1.20% of Mn; 0.40 to 0.60% of Cr; 0.60 to 0.80% of Ni; 0.20 to 0.30% of Mo; not greater than 0.025% of P, not greater than 0.020% of S, 0.02 to 0.03% of V, 0.03 to 0.05% of Nb, not greater than 0.20% of Cu, and the balance of Fe. The low-carbon equivalent high strength and toughness cast steel has the beneficial effect that micro-alloying technology is introduced to the production of low-carbon cast steel, so that the strength of material and low-temperature toughness can be greatly improved on the premise that high welding performance is kept, and the demand of a key part of a gold mine train, namely, a supporting shaft, can be completely met.
